Android使用javamail收发邮件

浏览数：28 / 时间：2015年06月11日

Android里访问网络、收发短信都还是经常用到的功能，但是这次需求是可以收发邮件，网上搜了下，这里转一个，博主写的几个工具类确实非常好用，转帖过来，下面是需要用到的资源和工具类文件

在发送多用户邮件中我添加了发送带附件的邮件的代码

1 发送邮件

今天学习了一下JavaMail，javamail发送邮件确实是一个比较麻烦的问题不用第三方邮件程序。为了以后使用方便，自己写了段代码.

Javamail-Android配置步骤：

下载Android版本JavaMail包，additional.jar、mail.jar和activation.jar，下载地址JavaMail-Android

在项目与src同一目录级别下，新建文件夹lib，将下载的3个jar包放入该文件夹

右键->Properties->Java Build Path->Libraries，选择Add External JARs，找到项目下lib目录的3个jar包

我的代码有三个类：
第一个类：MailSenderInfo.java

01
package com.util.mail;
02
/**

第三个类：MyAuthenticator.java

public MyAuthenticator(){

publicMyAuthenticator(String username, String password) {

this.userName = username;

this.password = password;

protected PasswordAuthentication getPasswordAuthentication(){

return new PasswordAuthentication(userName, password);

18
}
下面给出使用上面三个类的代码：
01
public static void main(String[] args){
02

//这个类主要是设置邮件

MultiMailSenderInfo mailInfo = newMultiMailSenderInfo();

mailInfo.setMailServerHost("smtp.163.com");

mailInfo.setMailServerPort("25");

mailInfo.setValidate(true);

mailInfo.setUserName("[email protected]");

mailInfo.setPassword("**********");//您的邮箱密码

mailInfo.setFromAddress("[email protected]");

mailInfo.setToAddress("[email protected]");

mailInfo.setSubject("设置邮箱标题");

mailInfo.setContent("设置邮箱内容");

String[] receivers = newString[]{"***@163.com", "***@tom.com"};

String[] ccs = receivers; mailInfo.setReceivers(receivers);

mailInfo.setCcs(ccs);

//这个类主要来发送邮件

MultiMailsender sms = newMultiMailsender();

sms.sendTextMail(mailInfo);//发送文体格式

MultiMailsender.sendHtmlMail(mailInfo);//发送html格式

MultiMailsender.sendMailtoMultiCC(mailInfo);//发送抄送

最后，给出朋友们几个注意的地方：
1、使用此代码你可以完成你的javamail的邮件发送功能、发多个邮箱。三个类缺一不可。
2、这三个类我打包是用的com.util.mail包，如果不喜欢，你可以自己改，但三个类文件必须在同一个包中
3、不要使用你刚刚注册过的邮箱在程序中发邮件，如果你的163邮箱是刚注册不久，那你就不要使用“smtp.163.com”。因为你发不出去。刚注册的邮箱是不会给你这种权限的，也就是你不能通过验证。要使用你经常用的邮箱，而且时间比较长的。
4、另一个问题就是mailInfo.setMailServerHost(“smtp.163.com”);与mailInfo.setFromAddress(“[email protected]”);这两句话。即如果你使用163smtp服务器，那么发送邮件地址就必须用163的邮箱，如果不的话，是不会发送成功的。
5、关于javamail验证错误的问题，网上的解释有很多，但我看见的只有一个。就是我的第三个类。你只要复制全了代码，我想是不会有问题的。

6、然后在Android项目中添加网络访问权限
